Report Overview
In November 2025, an updated SUBARU SOLTERRA was released.
The vehicle is equipped with a new BluE Nexus eAxle incorporating a new DENSO inverter core module. Compared with the previous Si RC-IGBT inverter, the new design uses double-sided-cooled SiC MOSFET power modules, closely positioned capacitors, and an optimized carrier frequency, reducing power loss by approximately 70% and inverter size by approximately 30%.
This report presents a circuit analysis of the gate-driver board installed in the inverter core module of the front eAxle.
A teardown report of the inverter core module is also available.
